In BMP assays grass silage produced 400 L CH4 kg-1 VS. Slurry, collected from a dairy farm, produced 239 L CH4 kg-1 VS. On a fresh weight basis, grass silage produced almost 7 times more methane than slurry (107 m3 CH4 t-1 compared to 16 m3 CH4 t-1). Co-digestion trials indicated that biomethane yields decreased by between 4 % and 11 % compared with predictions based on mono-digestion yields. The resource assessment suggested that grass silage from 1.1 % of grassland
digested on a 1:1 VS basis with slurry would allow compliance with the 2020 RES-T target in Ireland.
